This week for our human body unit we learned about our heart. We read this Let’s Read and Find Out Science book on the heart, Hear Your Heart.
It’s full of great information at just the right level.
While we read the kids coloured their heart to paste onto their body outlines. Here’s Jitterbug’s:
And here’s Ladybug’s. The colouring page tells you what colours to use, but Ladybug is welcome to use whatever colours she wants!
Then we listened to our heartbeats with a stethoscope. I believe I got the stethoscope here from CBD. The kids were keen to listen to the baby’s heartbeat, and tried, but of course it doesn’t work with just a stethoscope!
We tried to find our pulse, which is tricky for kids. After some effort we used this Instant Heart Rate app to track our pulses. You press your finger up against the camera and it measures your pulse. Pretty neat. Dad was home sick that day and he had it on his phone, otherwise I wouldn’t have known about it.
Then the kids raced up and down the driveway a few times to see if their pulse was any faster.
It was a bit difficult to get the younger two to hold still enough, they kept moving their finger so it didn’t measure accurately. But they had fun running anyway.
Ladybug especially insisted on participating in the running part!
We did a couple more printables, this one is a circulation wheel. As you turn the wheel you learn what happens to the blood in each place in your body.
This one helps illustrate how the blood flows through the heart, to the lungs, back to the heart, and out to the body.
I wanted to do this really neat activity where you place a bit of clay on your wrist over your pulse, put a toothpick in the clay and watch it vibrate to see your pulse. I tried it out on myself and really couldn’t get it to work well, so I didn’t try it with the kids. Maybe someone else will have better luck!
Next up: kidneys and bladder. No extra activities, so we’ll probably do the cells this week too. (See here for the resources we are using for our human body unit.)
